We begin with the woman who allegedly stalked alec baldwin, taking the stand in her own defense. Claiming she had a love affair with the actor. She is behind bars this morning. And the judge could decide this case today. Ron claiborne has the latest. Including the new surveillance video revealed overnight. Reporter: The alleged stalker, genevieve sabourin, is in jail this morning, when she continued with outbursts in the courtroom. That's how her day began. What followed was her testimony about a sexual encounter with alec baldwin, that she says he pursued. Genevieve sabourin, caught on camera inside alec baldwin's apartment building. This shows her moments before her april 2012 arrest for harassing and stalking the actor. The prosecution's final witness wednesday, baldwin's doorman. He testified when sabourin showed up that easter sunday, hilaria baldwin told him she was a stalker. Sabourin was real mad, he said. And started to say that she, hilar hilaria, was an expletive and a prostitute. That's how they treat normal people. They use fear. Reporter: This morning, sabourin is in jail. A judge sentencing her to 30 days for contempt of court, after her continued outbursts in court on wednesday. At times her tearful and rambling testimony, she asserts that she and baldwin began a flirtation in 2000. And after valentine's day 2011, a year before he married his current wife, hilaria, she says they met again. According to sabourin, baldwin told her, I want to make sure you have the night of your life. And says at the end of that night, they had sex at this new york city hotel. The next morning he said, he wanted to wake up every morning next to her. And make her an omelet every day for the rest of her life. Sabourin did concede that afterwards she sent him a lot of e-mails. But she insisted, I never intended to harass or annoy. And she admitted going to his long island home the week he proposed to hilaria. But was only seeking closure. Are you a stalker? Did you stalk him? Reporter: Baldwin denies he ever had sex or a relationship with sabourin. And the baldwins, they witnessed none of this. They didn't attend the trial wednesday. But they'll be monitoring it today, when following lawyers' summations, the judge is expected to hand down the sentence. She faces 90 days in jail if convicted of all five counts of stalking. That would be on top of the 30 days she's gotten for contempt. Dan abrams is here to weigh in on this. Not a jury. Just a judge that will decide. The contempt charge. How will that possibly factor in? It's a separate charge. As a practical matter, it has to be connected. This is the same judge who is going to be deciding her fate. She is accused of stalking and harassing. She's effectively harassing the court at this point. So, to think this is going to be completely separate, I think would be foolish. You can count on the fact that her lawyer has to be furious at her that she kept yapping away in court. She couldn't help herself. How important is it, whether or not she did have a romantic relationship with alec baldwin? Whether he was promising to make her omelets every day or whether she was the omelet of the day, the bottom line is, whether they had a romantic relationship, this thing is not going to be, shall we say, over easy for her, even if they did. Thank you. Thank you very much, ladies and gentlemen. I'll be -- I'll be at the performing arts center on thursday and sunday. The bottom line is, that you still can have had a relationship. She could have been involved with him to some degree. And that doesn't change the fact that she could have been harassing him and stalking him. The legal question there, would a reasonable person in his position have felt threatened? And what was her intent? Was her intent to annoy? Harass? Et cetera. She's in big trouble here as a legal matter. They're not that serious crimes. That misdemeanor, up to 90 days. It's going to be unlikely the judge will rule in her favor. We're going to find soon. You're going be pelted with eggs. Baked or fried. Thank you for that. We have an update on the
